Title: Bottle cap and valve assembly for a bottled water station
Inventor: BURROWS BRUCE D
IPC: B67D1/08
Filed: 1992-09-23
Abstract: An improved bottle cap and valve assembly are provided in a bottled water station (10), wherein the station (10) includes an actuator probe (26) for engaging a bottle cap (20) on an inverted water bottle (12) installed onto the bottled water station (10). The actuator probe (26) includes a probe head (68) for opening a bottle cap valve member (24), thereby permitting downward water flow from the bottle (12). Dual flow paths formed through the actuator probe (26) permit smooth downward water flow through one flow path, substantially without glugging, to an underlying station reservoir (16) simultaneously with upward air flow through the other flow path from the reservoir (16) to the bottle interior. In the preferred form, the valve member (24) is integrally molded as part of the bottle cap (20) and configured to be severed therefrom upon engagement with the probe head (68). The preferred probe head (26) captures and retains the severed valve member (24) in a position for slide-fit sealing re-engagement with the bottle cap (20) when the bottle (12) is removed from the station (10).

Abstract: The spray unit lies downstream, in-line with an extrusion press and serves to cool metallic sections (18) in particular sections of aluminium or an aluminium alloy from all sides. The cooling medium emerges from spray nozzles programe-controlled in the direction of the section (18). The distance (a, b, d), the cross-section distribution and the direction of the spray nozzles are adapted specific to the geometrical shape and distribut-ion of mass in the section (18). The optimum parameters are determined and stored in the unit processor. The spray nozzles (28) are arranged in nozzle beams (22) running in the direction (16) of the extruded section (18). The nozzle beams (22) comprise at least one longitudinal water channel (W', W:" and two longitudinal air channels (A', A"), whereby cross-intersecting channels (31, 33) branch off from the water channels (W', W") to the spray nozzles (28) and the air channels (A', A") terminate in air gaps (39, 41) which are directed towards the nozzle outlets (38).   The extruded sections (18) are passed through the spray unit and cooled, at a rate that exceeds the critical cooling rate specific to the material, by a programme controlled, sprayed cooling medium in a manner that takes into account the shape of the section and the distribution of mass in the section. Using uniform cooling on all sides, sections (18) that are extrud-ed straight can be kept straight, while sections that are distorted on extrusion can be corrected with respect to bending and/or twisting by non-uniform cooling.

Abstract: Some delicate clothes can only be washed by hand and hanged to dry. Others are so crumpled in the dryer that ironning them gives headaches. Where then to wash and most importantly, where to hang the clothes to dry, avoiding the messie dripping of water (which can also cause damages) and having a support strong enough to carry the wash load. The best place in the traditional appartments for washing the clothes is in the bathtub and over it for hanging them to dry. It is very convenient after washing the clothes to only stand up and hang them to dry. The wash load can be hidden from sight by pulling the shower curtain and the device removed leaving no trace since it is self supported.

Title: Method for channel utilization in extended spectrum communication systems
Inventor: PATSIOKAS STELIOS J
IPC: H04M1/72511
Filed: 1993-04-28
Abstract: A base station (12) allocates radio channels to radio telephone handsets (20) in a second generation cordless telephone (CT2) communication system (10) by scanning each channel in a first band, and scanning each channel in a second band to measure an RSS level for each channel scanned. The base station scans the second band at a rate that is substantially faster than the rate at which it scans the first band. If a link request is received (119) on a first channel within the first band, from a calling radio telephone, the base station determines whether the first channel has an RSS level above a predetermined threshold (121). If the RSS level of the first channel is above the threshold, and the calling radio telephone handset is capable of operating on the second band, the base station re-assigns a second channel, that is within the second band, to the calling radio telephone handset.

Title: Polyurethane backed textiles having improved flame retardancy and method for the preparation thereof
Inventor: MOBLEY LARRY W
IPC: A47G27/02
Filed: 1994-07-12
Abstract: ABSTRACT       Polyurethane backed textiles, particularly polyurethane backed carpets and carpet tiles can be prepared having a critical radiant flux of greater than or equal to 0.45 watts/cm2.  The improved flammability performance is achieved by using ZnCO3 or MgCO3 as flame retardants.  The use of the flame retardants of the present invention allows for improved flammability properties compared to otherwise similar backed textiles prepared with conventional flame retardants. The flame retardants of the present invention can have no substantial affect on polyisocyanate reactivity which can minimize reformulation experimentation.

Title: Optical-fibre passively mode locked laser generator with non-linear polarization switching
Inventor: FONTANA FLAVIO
IPC: H04B10/556
Filed: 1994-09-16
Abstract: ABSTRACT     A passively-mode-locked laser generator having an active optical fibre and fibre pumping means adapted to cause the generation of an emission signal in the fibre, a polarization control means, signal extraction means and at least one optical component with transmisiveness depending on polarization is disclosed.  The components are inserted in an optical fibre path that, for a pumping energy lower than a predetermined value corresponding to a linear propagation condition of the signal, gives rise to a polarization rotation of the emission signal through an angle causing the extinction of the signal itself within the optical component with transmissiveness depending on polarization.  For a pumping energy of a higher power than the predetermined value, the generator causes a polarization rotation of the emission signal through an angle corresponding to the transmission with low losses of only pulses of high peak power of the emission signal.
